- On 14 July 2015, diplomatic efforts by China, France, Germany, the Russian Federation, the United Kingdom of Great Britain and Northern Ireland, the United States of America and the European Union with the Islamic Republic of Iran culminated in the Joint Comprehensive Plan of Action. On 20 July, the Security Council adopted resolution 2231 (2015), in which the Council endorsed the Plan and called upon all Member States, regional organizations and international organizations to support its implementation. On 18 October 2015, the Plan came into effect and its participants began to take steps to implement their commitments.
- For the past five years, the Plan has been largely viewed by the international community as a testament to the efficacy of multilateralism, diplomacy and dialogue and a success in nuclear non-proliferation. I have consistently believed that the Plan is the best way to ensure a comprehensive, long-term and proper solution to the Iranian nuclear issue, as well as to contribute to regional and international peace and security. I note the continued commitment of its participants to preserve the Plan, and the importance of the Plan working for all, including by providing tangible economic benefits for the Iranian people. I have encouraged all States to support the Plan and believed that issues not directly related to the Plan should be addressed without prejudice to preserving the agreement and its accomplishments.
